Description

Golf club head with carbon fiber hitting panel

The present invention relates to a golf club head, in particular to a golf club head including a carbon fiber hitting panel.

In order to improve the hitting performance of wood-type golf club heads, the current research and development direction is mainly through material changes and structural weight reduction, in order to change the weight configuration of the club head and adjust the center of gravity of the club head. , optimize the moment of inertia (MOI) of the golf club head when hitting the ball, and improve the flight distance and flight direction stability of the golf ball after being struck.

Among the many known wood-type golf club heads, some club heads are made of a heterogeneous material combination of parts made of carbon fiber materials and parts made of metal materials. For example, the club head is split into a club head body, There are multiple components such as the hitting panel part and the top cover, and the club head body is equipped with a weight component. Some of the components in the aforementioned club head body, hitting panel part, and top cover are made of metal materials, and the remaining parts are made of carbon fiber materials. Generally speaking, a common wood-type golf club head uses a carbon fiber head body front end combined with a metal hitting component, or a metal club head body front end combined with a carbon fiber hitting component.

Among the aforementioned known golf club head products related to the combination of heterogeneous materials, when the front end of the club head body made of metal is combined with the hitting component made of carbon fiber, a panel assembly hole is preset at the front end of the club head body. , and then embed the plate-shaped hitting panel portion in the panel mounting hole of the club head body.

Although the existing club head structure of the aforementioned metal club head body front end combined with a carbon fiber hitting component can reduce weight by using lightweight carbon fiber materials, the carbon fiber hitting surface The plate accounts for a small proportion of the overall weight of the club head, and the effect of the weight reduction transferred to the weight allocation of the club head is limited.

Furthermore, in the combined structure in which the front end of the club head body is embedded with the hitting panel portion, since the panel mounting hole at the front end of the club head body and the plate-shaped hitting panel portion are only in a flat connection structure, the bonding strength between the two is poor. insufficient. When hitting the ball, due to excessive impact shear force, the joint between the hitting panel and the club head body may easily crack, or even the hitting panel may fall off. Further structural improvements are necessary.

The object of the present invention is to provide a golf club head including a carbon fiber hitting panel, so as to solve the problem that the existing golf club head is combined with a carbon fiber hitting panel at the front end of the metal club head body to reduce weight and transfer it to the weight of the club head. The effect of the configuration is limited, and the combined structure in which the front end of the club head body is adhered and fixed to the hitting panel is prone to problems such as the hitting panel falling off due to excessive impact shear force.

In order to achieve the above object, the golf club head system including a carbon fiber hitting panel proposed by the present invention includes: a hollow club head body, which includes a metal club head base, and the front end of the club head base has a panel fixed The frame part, and a pole sleeve installation part extending upward from one side of the panel fixing frame part, a panel assembly opening is formed in the panel fixing frame part, and a panel bearing wall located at the inner periphery of the panel assembly opening, the The panel load-bearing wall is provided with a fitting recess with an opening facing forward; and a carbon fiber hitting panel, which is fixed in the panel fixing frame portion of the club head base. The carbon fiber hitting panel includes a hitting panel portion and A fitting convex portion is provided on the back edge of the batting panel portion. The batting panel portion is matched and fitted into the panel assembly opening of the panel fixed frame portion to form a batting surface, and the panel bearing wall is fixedly mounted to carry the batting surface. In the batting panel part, the fitting convex part is embedded in the matching fitting recessed part in the panel bearing wall.

Through the aforementioned invention of the overall structure of the golf club head, it has at least the following advantages:

1. Optimize bonding strength and hitting performance: The golf club head of the present invention mainly fixes a carbon fiber hitting panel in the panel fixed frame part of the front end of the hollow club head body.

The panel fixing frame portion at the front end of the club head body is provided with a panel assembly opening that matches the hitting panel portion. The panel bearing wall inside the panel assembly opening Forming a fitting recess with the opening facing forward, the carbon fiber batting panel is matched and combined with the panel assembly opening of the club head body. The panel load-bearing wall is located at the back periphery of the hitting panel of the carbon fiber batting panel to provide fixation and load-bearing. , as well as the combined structure of matching the fitting convex part with the fitting recessed part of the panel load-bearing wall inside the panel assembly opening, so that it can effectively optimize the bonding strength and hitting performance between each other, and avoid the carbon fiber of the existing golf club head. The hitting panel is prone to falling off of the hitting components due to excessive impact shear force.

2. Increase the weight allocation margin of the golf club head: As mentioned above, the golf club head of the present invention is based on the club head body at least partially made of metal. In addition to reducing weight by providing a carbon fiber hitting panel, Furthermore, a fitting recess is provided in the panel bearing wall in the panel fixing frame at the front end of the club head body to reduce the amount of metal material used in the club head body. In addition, a carbon fiber batting panel is used to fit the protrusions on the back edge of the hitting panel part. The entire body fills the physical space of the fitting recess, allowing the golf club head to simultaneously reduce weight while maintaining sufficient bonding strength between the club head body and the carbon fiber hitting panel, thereby increasing the weight allocation margin of the golf club head. Spend.

The golf club head of the present invention can further use carbon fiber materials or high molecular polymer materials for at least part of the top cover and bottom plate located at the top of the metal club head body in the hollow club head body, so that the club head body can maintain its shape. On the basis of the required strength, the weight is reduced by using carbon fiber materials or polymer materials for the top cover or bottom plate, thereby changing the weight configuration of the club head and adjusting the center of gravity of the club head to optimize golf club head impact. The moment of inertia (MOI) of the ball.
